本文用水杨酸、8-羟基喹啉、硝酸银、蔗糖、蒸馏水配制了五种保鲜剂,其中设置了三种不同浓度的水杨酸配方。实验结果表明:四种保鲜剂配方在促进非洲菊花朵开放、切花吸水、增大花径、维持切花水分平衡几个方面均优于对照(蒸馏水),同时水杨酸的保鲜效果明显优于硝酸银。实验筛选出水杨酸的最佳浓度为75mg/L。
In this paper, salicylic acid, 8-hydroxyquinoline, silver nitrate, sucrose, distilled water preparation of five kinds of preservatives, which set three different concentrations of salicylic acid formula. The results showed that the four kinds of preservative formulations were better than the control (distilled water) in promoting gerbera flower opening, water absorption of cut flowers, increasing flower diameter and maintaining the water balance of cut flowers, and the preservative effect of salicylic acid was significantly better than Silver nitrate. The optimum concentration of salicylic acid was 75mg / L.
